“…As an alternative, p-type semiconductors have been shown to be effective gas sensors, which are rugged and robust and do not suffer from some of the limitations of n-type semiconductors [8]. Some of these sensors are already commercially available, for example, ammonia sensors of Cr 2-x Ti x O 3 [9,10], and rare-earth metal-oxide based LnFeO 3 perovskite sensors for NO x detection, where Ln = La, Sm, Gd, and Dy [11].…”

for the final review of the manuscript, for writing the foreword and for providing decisive comments. Many thanks also to Prof. Kostas Mavrias, Emeritus, Professor of Constitutional Law at the Law School of the National and Kapodistrian University of Athens and President of the Scientific Council of the Hellenic Parliament for his push towards scientific excellence and his steady support throughout the years. I would also like to underline the unseen contribution of many of my colleagues and fellow scientists, too numerous to mention, for their support and the fruitful discussions throughout the drafting phase.Many thanks also to the friends and colleagues from the Hellenic Optical Character Recognition (OCR) Team, for their true dedication to science and innovation that has always been a source of inspiration to me. Dimitris Garantziotis deserves a special mention for his valuable contribution in the last phase of drafting. Lots of thanks go to Antonia Becou who professionally redesigned all graphic material in the book. Last, but not least, I would also like to thank Bruce Philip Todd, not only for the linguistic assessment and support, but also for the out-of-the-box general comments.Above all, I would like to thank my family for all the support that gives me strength to carry on. viii ix About the AuthorDr. Fotios Fitsilis has over 20 years of professional experience in science positions within in both the private and the public sector. Since 2008, Dr. Fotios Fitsilis is Head of Department for Scientific Documentation and Supervision and lead researcher at the Scientific Service of the Hellenic Parliament. While operating on a global scale, he has been active in fields ranging from telecommunications and logistics to management and good governance, which has included recent papers on e-governance and institutional development including improvements to parliamentary oversight committees. Dr. Fitsilis has been visiting Professor for parliamentary procedures and legislative drafting at the Universidad Complutense de Madrid. In 2017, he founded the Hellenic OCR Team, a crowdsourcing initiative for the study of parliamentary data. Dr. Fitsilis has an academic background in Law (LL.M. in International Law), Economics (Diploma in Financial Engineering) and Engineering (Diploma in Electrical Engineering), while also holding a doctoral degree in Electrical Engineering.

“…A chemical/gas sensor provides an electrical/optical output in response to chemical and physical interactions with chemicals/gases. In particular, the gas sensors have been used for various industrial and/or safety applications and chemical such as a) determination of gas leakage [41,[47][48][49], novel LPG sensitive materials working in the entire range of least explosive limit (LEL) to upper explosive limit (UEL) [30][31][32]. Nanostructured perovskite materials can improve the sensing properties of the sensor due to high surface-to-volume ratio characteristics.…”

The perovskite structure is adopted by many compounds in solid-state chemistry. The sensitivity, selectivity, and stability of many perovskite nanomaterials have been devoted the most attention for chemical sensors. They are capable to sense the level of small molecules such as O 2 , NO, and CO. This chapter provides a comprehensive overview of perovskite nanoscale materials that concentrate on chemical sensors. The perovskite structure, with two differently sized cations, is amenable to a variety of dopant additions. This flexibility allows for the control of transport and catalytic properties, which are important for improving sensor performance. We devote the most attention on the synthesis, structural information, and sensing mechanism. We will later elaborate on the development mechanism of chemical sensors based on perovskite nanomaterials. We conclude this chapter with the personal perspectives on the directions toward future works on a novelty of nanostructured chemical sensors.
